Don't really wanna go naming people as they may not like it, but all I will say is the girl my wife knows is a famous gravure idol everyone who knows Japanese models will know her and my friend in AV is very famous, met some friends in the industry through her too who I am not sure are that well known or not and they seem ok.
But in total I know 3 AV girls 1 gravure girl and met another gravure idol.
My understanding is some are nice others are bitches but my friend is a lovely girl and very down to earth, quite often go for a meal, coffee etc in Ginza, Shibuya or Ueno.
